I think grub and grub2 rely on a working bios, and don't plan to have
as much hardware initialization as u-boot may have. There is no bios
on the Sheevaplug, and the first code run is the u-boot directly.

I changed the boot attributes in order to get modularity on the
bootloader, agreeing with pierron on the best ways to get it done.
Grub still lacks on modularity even after my changes.

The generationsDir bootloader isn't specific for u-boot (and I even
only mentioned u-boot in the commit message), but helps a lot if a
user doesn't want nixos to care on managing the bootloader. Although
the current nixos supported not managing grub (not defining
grubDevice), I don't know how a user should have managed the boot
loader on his own before generationsDir.

Amike,
